What Is Bleach?
Bleach is a chemical product used to lighten or remove color from hair. It works by breaking down the natural pigments in the hair, allowing the color to be changed. There are several types of bleach available, and the strength of the bleach is measured in volume. The higher the volume, the stronger the bleach.
